<p>I know I shouldn’t, but could anybody help more, or like lead me how to figure out these problems. I realize they aren’t particularly hard but when I think its one answers, something makes me second guess myself. Hope you can help.</p>
<p>1.True or False: The function KE(v)=1/2kv^5, given that k is a constant, is an example of power function.?</p>
<p>2.True or False: Is the function f(x)=9x^(5/3) an example of power function?</p>
<p>3.The Data:</p>
<p>1.Age 2.Life expectancy (years)</p>
<p>10 66
20 56
30 47
40 37
50 29
60 20
70 14
80 8</p>
<p>The correlation of the scatter plot for the data given below of U.S. life expectancy can be described as </p>
<p>a. strong positive
b. strong negative
c. weak positive
d. weak negative</p>
<p>4.True or False: Is the function k(x)=4x-5x^2 an example of a polynomial function?</p>

<li>They gave me this grpah and asked me to match these functions with the lines (A-H)</li>

<p>a) f(x)=(1/2)(x^-5)
b) f(x)= -x^(5/3)
c) f(x)= 1.7x(2/3)</p>
